Dinan 21-26 BMW 430i/M440i (G22/G23/G26) Adjustable Front & Rear Sway Bar Set - 28mm & 19mm

Every Dinan tuned anti-roll bar on the other hand is built and tuned specifically for each targeted BMW chassis to provide a more responsive and crisp experience. By reducing the amount of body roll your BMW is kept much closer to level than stock (while still allowing just enough body roll) to improve mechanical grip. This improvement gives the driver a much more planted and confident feeling in every corner making it a must-have upgrade for back road and track enthusiasts alike. Front: 28mm - Rear: 19mm - Adjustable - G20/G22/G23/G26/G42 Dropping of the subframe is required so professional installation is highly recommended.

Enhance your BMW's handling and stability with the Dinan Part Number D120-0630 adjustable sway bar set, designed specifically for models including the 2020-2022 BMW 430i and M440i in G22, G23, and G26 chassis. Crafted from high tensile strength alloy steel with tubular hollow construction, these sway bars offer maximum strength while minimizing weight, providing a responsive and confident driving experience. The front bar, increased to 28mm from the stock 26.1mm, and the rear bar, enlarged to 19mm from 17.8mm, deliver significantly increased stiffness—up to 50% front and 54-66% rear—reducing body roll during aggressive cornering and improving mechanical grip. The rear bars are two-hole adjustable, allowing fine-tuning to match driving conditions or personal preference, making this upgrade suitable for both spirited back road driving and track days.
Installation requires dropping of the subframe, so professional installation is highly recommended to ensure proper fitment and safety. Included polyurethane bushings and grease facilitate smooth operation and durability, while the increased stability at the limit provides greater confidence in high-performance driving scenarios. This sway bar set is an essential upgrade for enthusiasts seeking to refine their BMW’s handling dynamics by reducing body lean and enhancing mechanical grip without compromising comfort. Its compatibility spans a variety of BMW models, offering an excellent balance of performance and adjustability for a precise driving experience.
